IMPROVEMENT IN MACHINERY FOR THE MANUFACTURE OF TUR NED SHOES.

Specification forming part of Letters Patent No. 146,654, dated January20, 1874; application filed December 17, 1873.

To all whom it may concern:

Be it known that we, CHARLES W. COLL- YER and EDWARD C. SYMoNDs, both ofMarblehead, in the county of Essex and State of Massachusetts, haveinvented an Improvement in the Manufacture of Turned Shoes; and we dohereby declare that the following, taken in connection with the drawingswhich accompany and form part of this specification, is a description ofour invention sufficient to enable those skilled in the art topractice'it.

In the manufacture, in boot and shoe making, of what are known as turns,the sole and upper are united wrong side out, and are then reversed orturned, and the process of turning is by far the most laborious handlabor connected with boot and shoe manufacture.

The hand process it is unnecessary to describe, but workmen who performthe turning are injured in body by the operation, and are unable to workmany days in succession.

The object of our invention is to accomplish the turning by a machineoperation;

and'our invention consists primarily in an ortion. Fig. 2 is a plan ofthe same. Fig. 3 is an end elevation.

at denotes a last, upon which the sole and upper of the boot are lastedand connected. This last is mounted upon a pin, b, extending up from aslide, a, the slide moving between guides d, so that the last can becarried up to avstati'onary last, 0, orback therefrom, the slide beingdrawn back when a last with a shoe to be turned is to be placed upon thepin, and the last a being then moved up to the last e for the turningoperation. The sta: tionary last is mounted upon the top of a bow, f,extending up from the main frame or table 9, and upon this table is acarriage, h,

. shank 8.

are jointed two crossing bars, 0, having, at

their bottom ends, a pair of jaws, p, which, when the arm I isdepressed, will gripe the boot at the opposite sides of the counter, thebars being drawn together to tighten the gripe by a suitable spring, q.Just back of the jaws is a spring, 1', that bearsupon the sole in theshank, and, as the arm lis raised, the jaws draw up the back or heel endof the boot from the last, the spring holding the shank down.

to the last. The carriage h is then drawn back, and the jaws holding thequarters peel off the fore part of the boot from the last and draw itover the stationary last 0. The last a is made short, ending at theshank s, or being without a heel, and when the jaws 1) have laid downthe fore part of the shoe over the last,

6, the heel partis left projecting beyond the At the end of the last 0is a head, t, upon a piston, a, passing through a stationary tube, '0,extending up from the table 9.

When the fore part of the shoe has been turned the heel part is leftover the head t,

the bottom edge of the counter being over a groove, made upon the head.The operator then seizes the edge of-the upper at the heel and raisesthe head, the counter and heel being turned over the head by the upwardmotion of the head, in connection with the action of the operator, todrawn down the upper. gear mechanism, consisting of a winch-shaft,

we, having a pinion meshing into a gear that works into a rack on theunder side of the carriage, and the piston u may be raised by a lever,w,(pivoted at y, and connected at its outer end to a pedal, 2,) and throwndownby a spring, j.

We claim 1 1. The combination, with the boot-holding The carriage It maybe actuated by a last a of the stationary last 6, jaws 11, 21mm 1, postis, and carriage h, operating to strip and turn the shoe, substantiallyas described.

2. In combination with the jaws p, the spring 0-, for holding down theshank, substantially as described. I

3. In combination with the stripping'mechanism, the heel-turning head tand piston 21,

substantially as described.
